It's a double dose of Oresama Teacher! We're back to the main storyline, which is really quite interesting - and shocking! Lots of surprises are in store! I've been wanting to do a double release for a while, and I finally got the chance to really work and catch up a bit on the releases. We're just 2 chapters behind the Japanese releases! Anyway, these new chapters (and the next) are quite exciting!
